Standard Procedure - Filling: 5.9L

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The diesel engine is equipped with two one-way check valves (jiggle pins). The check valves are used as a servicing feature and will vent air when the system is being filled. Water pressure (or flow) will hold the valves closed.

Clean cooling system prior to refilling. Refer to Standard Procedure .

Close radiator drain plug.
If using funnel 8195:
1. Remove cooling system pressure cap. Attach Filling Aid Funnel (special tool #8195, Funnel), to coolant pressure container filler neck.
2. Use the supplied clip to pinch overflow hose.
3. Pour coolant into the larger section of Filling Aid Funnel (the smaller section of funnel is to allow air to escape).
4. Add coolant until some coolant remains in the funnel and no more air bubbles appear in the fluid.
5. Remove clip from overflow hose.
6. Allow coolant in Filling Aid Funnel to drain into overflow chamber of pressure container.
7. Remove Filling Aid Funnel. (special tool #8195, Funnel)

NOTE:
The 8195A does not require pinching off the overflow hose. The adapter seal prevents liquid from entering the overflow during coolant fill.
If using Special Tool 8195A:
1. Select the appropriate fitting extension (3) and locking ring (2) and attach to the fill neck of the cooling system.
2. Make sure the adapter seal fits firmly against the inside of the fill neck base to ensure a good seal. After the extension and locking ring are installed, make sure the extension can not be moved. This will confirm a good seal.
3. Attach the funnel (1) to the extension (3) and fill with coolant.
4. Add coolant to the funnel.
  Continue to add coolant until it is free of bubbles.
5. Install the stopper (4) into the funnel base. The stopper will prevent the fluid that is left in the funnel from spilling out when separated from the extension.
6. Remove the funnel, extension and locking ring and install the cap.
Fill coolant recovery container to the FULL mark.
Start and operate engine until thermostat opens. Upper radiator hose should be warm to touch.
Accelerate engine from idle to 2500 RPM five times.
Shut off engine. Allowing cooling system to settle. Fill coolant recovery container to FULL line.
Start and operate engine. Take vehicle for a test drive till operating temperature is reached.
Shut off engine. Allow engine to cool. Fill coolant recovery container to FULL line.
The volume of coolant added to the engine must be within 1.5 quarts of the volume drained. If this requirement has not been met, repeat steps 1 - 13.
Install radiator cap.
